Title: An optical crosspoint switch using vertically coupled waveguide structure
Inventor: YU SIYUAN
IPC: G02F1/365
Filed: 2000-03-30
Abstract: An optical crosspoint switch structure is disclosed. The switch permits light signals to be diverted from any arbitrary number of input ports to any or several of an arbitrary number of output ports. The switch consists of two groups of intercepting optical waveguides formed on a planar substrate, which are the input and output waveguides respectively. At each intersection, another waveguide is formed above the input and output waveguides. Optical coupling between this upper waveguide and the input/output waveguides is controlled by an electrical or optical signal. The upper waveguide has a corner mirror at the intersection. When the control signal allows, light couples from the input waveguide to the upper waveguide. After being reflected by the corner mirror, the light couples from the upper waveguide into the output waveguide. The upper wave-guide incorporates the active switching element. Allowing high modulation depth and low crosstalk level.

Abstract: A method of providing a zoom feature for a handheld computer is described. T he method uses a combination of software and hardware to provide the display zo om without using significant processor resources, or adding dedicated zooming hardware to the display. The method includes storing the image for the displ ay in a memory and using the processor and the memory controller to store the image so that when it is retrieved by the display controller, for transfer t o the display circuit, it is already zoomed in a fist direction. The method al so includes using a pixel replication circuit to provide the replication of pixels in the other direction. The pixel replication cicuit takes a row of pixels and doubles each pixel in the row. This combination allows for the consumption of relatively little processing resources and does not require extensive additional hardware. In some embodiments, the operating system software and other software that writes to the display memory is modified so  that write operations occur multiple times to provide the zoom effect. In other embodiments, the display software is modified to leave empty rows in t he display memory. A memory access controller can map a request by the display controller for pixel data from an empty row onto the corresponding row with pixel data.

IPC: A01D47/00
Filed: 2002-02-08
Abstract: A crop harvesting header includes a cutter bar arranged across a forward edge of a header frame structure, a draper or auger transport arrangement for transporting the cut crop for further processing, and a reel mounted on reel arms for controlling movement of the crop in the area over the cutter bar with the reel having a plurality of reel bats at spaced positions around the reel axis each reel bat having reel fingers projecting generally radially outwardly from the reef axis, the reel bats all lying on a common bat circle around the reel axis so that rotation of the reel causes the reel bats to follow a path of movement lying on the bat circle. A  non-circular stationary cam track surrounds the reel axis within the bat circle so that the end most fingers of the bats are located in line with the cam and immediately adjacent the end sheet. Each bat is pivoted by a crank attached to the bat and a control link having one end freely pivotally connected to the outer end of the bat lever and having a cam follower the other end. A pulling link communicates rotation of the reel to the control link such that the cam follower thereof is caused to move along the cam track at a predetermined position therein. The crank is adjustable relative to the control link to change bat finger angle to provide a change in crop lift before the cutter bar while maintaining finger pattern. The cam location is adjustable around the reel axis to change the finger pattern.

Inventor: WINOWICH DERRELL M JR
IPC: D04B9/16
Filed: 2002-04-18
Abstract: A device knits together a tubular structure of continuous fibers with a stitch yarn, to provide a reinforcing substrate, especially for use with roofing materials. The device brings together first and second sets of the continuous fibers at a cylinder with a plurality of latch needles. The first set of fibers enter the cylinder radially in interstitial spaces between adjacent needles. At least one continuous fiber constituting the second set of fibers enters the cylinder tangentially at an insertion point. Axial manipulation of the needles at the insertion point results in knitting the stitch yarn around the intersecting first and second continuous fibers, resulting in the knitted tubular structure. The manipulation is achieved by rotating the means by which the second fibers and the stitch yarn are introduced, as well as the means for manipulating the needles, in a stepwise sequential manner around the circumference of the cylinder.

Title: Method of determining subsidence in a reservoir
Inventor: STONE TERRY WAYNE
IPC: G01V11/00
Filed: 2001-07-06
Abstract: A reservoir simulator first estimates rock displacement parameters (u, v, and w) representing rock movement in the x, y, and z directions. When the rock displacement parameters (u, v, w) are determined, ".epsilon.x,y,z" (the X,Y,Z elongation strains) and ".gamma.xy,yz,zx" (the shear strains) are determined since ".epsilon.x,y,z"  and ".gamma.xy,yz,zx" are function of "u", "v", and "w". When ".epsilon.x,y,z"  and ".gamma.xy,yz,zx"  are determined. ".sigma.x,y,z" (the elastic normal rock stress in x,y,z directions) and ".tau.xy,yz,xz" (the elastic shear stress) are determined since ".sigma.x,y,z" and ".tau.xy,yz,xz" are a function of ".epsilon.x,y,z" and ".gamma.xy,yz,zx". When ".sigma.x,y,z" and ".tau.xy,yz,xz" are determined, the rock momentum balance differential equations can be solved, since these equations are a function of ".sigma.x,y,z" and ".tau.xy yz,xz". When any residuals are substantially equal to zero, the estimated rock displacement parameters (u, v, and w) will represent accurate rock displacement parameters for the reservoir. When the rock momentum balance differential equations are solved, the rock displacement parameters (u, v, w), at an advanced time, are known. These rock displacement parameters (u, v, w) represent and characterize a subsidence in a seabed floor because subsidence will result from rock movement; and rock movement will result from a continual withdrawal of oil or other hydrocarbon deposits or other fluids such as water over a period of time from an Earth formation. This abstract of the disclosure is given for the sole purpose of allowing a patent searcher to easily determine the content of the disclosure in this application.
